Answer: C. 4x - 6y = 3
Step-by-step explanation:
We only need to find a line with the same slope.
We will put 4x - 6y = 3 in slope intercept
4x - 6y = 3
-6y = -4x + 3
y = 4/6 - 3/6
y = 2/3 - 1/2
There you have it, a line with the same slope, which means it's parallel.

Answer: Minimum sample size = 110
Step-by-step explanation:
Formula to find minimum sample size :
, where z = critical z-value for confidence level, s= sample standard deviation , E = margin of error
Given: E= 4 , s= 18
Critical z-value for 98% confidence = 2.327
So, 

Minimum sample size = 110
49b^2 -36 = (7b -6)(7b +6)
so because there you missed some signs in these wrote choices
